Yes, it's interesting how the polling for Hillary vs. McCain in some states was very different from what we saw with Obama:

There's no way of knowing.
Some of us (well, at least me) expected an Arkansas 'bounce-back' in 2016 because one of the very, very early polls showed her only a couple points behind several GOP candidates and even leading one or two of them... only for Arkansas to swing even more R.
